TYPE-WRITING MACHINE.

Application filed December 2,1913.

To all whom it may concern:

Be it known that I,.HENRY G. WISSMAN, a citizen of the United States, residing in Youngstown, in the county of Mahoning and State of Ohio, have invented certain new and useful Improvements in Type- Writing Machines, of which the following is a specification.

This invention relates to typewriting machines, and particularly to machines of that class in which work-sheets for loose-leaf ledger work or other bookkeeping purposes are collated upon a board which extends upwardly and rearwardly from the carriage of the typewriter, the sheets usually having regularly spaced perforations in their side margins, whereby they engage studs running along the sides of the sheet board, said studs being connected to carry the sheets around the platen after the sheets are collated, and to hold the sheets in proper relationship as they travel through the machine.

In using this class of machine, the work sheets are sometimes so large that it be comes necessary to make the collating 'board and its support much too extensive for the capacity of the typewriter.

The principal object of my improvements is to overcome this difficulty.

I connect the lower end of the sheetcollating board and its frame to the typewriter carriage, so as to travel therewith, and also provide an independent support for the upper end of said frame, said independent support comprising a slide or carrier and a track upon which it may move, the track being parallel with the rails along which the paper carriage of the typewriter usually travels.

Other features and advantages will hereinafter appear.

In the accompanying drawings, Figure l is a perspective view of my improvements I applied to an Underwood front-strike typewriting machine. F ig. 2 is a sectional side elevation of the improvement. Fig. 3 is a sectional front elevation to show the attachment of the sheet-supporting board to the paper carriage of the typewriter.

Said Underwood typewriting machine usually comprises acarriage 1 running on front and rear rails (the latter shown at 3), and having a platen-4; upon the front side of which strike type bars 5. The carriage is Specification of Letters Patent.

usually propelled by adriving spring under the control ofa letter-feeding mechanism operated by the type-keys, but it is not believed necessary to illustrate these parts.

From the rear of the platen extends upwardly and rearwardly a sheet-collating board 6, whose lower end 7 may terminate above the platen at the rear thereof. This board is supported upon cross bars 8, which at their opposite ends are bent down at 9 and secured to a pair of upwardly and rearwardly inclined rods 10, thus forming a frame; the rods being secured at their lower ends by screws 11 to plates or brackets 11 provided upon the ends of the typewriter carriage, whereby the frame is partly supported and is also caused to travel with the carriage.

The work-sheets may be laid upon a broad belt 13, which may be endless and at its lower end may be looped around the platen 4. Its upper end may run over a roll 14; said belt carrying studs 15 at each of its side edges, upon which to impale or collate the work-sheets. The upper end of the board 6 terminates just below the roll 14. By revolving the platen, the sheet-car- It is usual to arrange the sheets upon the studs, and then to advance the sheets upwardly, the sheets then turning with the belt around the roll 14, and then being carried down around the under side of the board with the belt, and thence under the platen and up in front thereof to printing position. As the sheets first travel up with the belt 13 their leadingedges run under the -forward edge of a guldmg apron 17, which sheets in conjunction with the platen 4.

The frame comprising the members 6, 8 and 10 is further supported upon a supplemental .carriage 22, which may be in the form of a bar having upper and lower grooves 23 to receive balls 24 running in grooved tracks 25; the latter carried upon arms 26 which are secured at 27 to the right rying belt 13 may be advanced or retracted. i

and left hand ends of the rear portion of the typewriter frame work 28. Opposite supports 29 extend up from said carriage and are secured at 30 to the. rods 10; said supports 29 being far enough apart to permit the belt 13 and the work-sheets to pass between them. Thus it will be seen that the sheet-collating board and its appurtenances, although very much over-size in respect to the typewriter carriage, are still firmly supported and freely movable, and do not unduly retard the letter-feeding movements of the typewriter carriage. This additional support for the collating board may be arranged high above the typewriter carriage and near the top of the collating board, as shown, so that the board structure, which is of light construction, is well supported at its upper part, which would be most liable to yield if unsupported.

The rods 10 may be further connected at their upper ends by a cross bar 30*, rigidly secured by means of nuts 31; and the paperguiding apron 17 may be fixed to brackets 32 secured on the opposite ends of said bar. The brackets may be connected by a stifi'ening rod 38, which may also serve as a convenient support upon which to hang carbon sheets while manipulating the work sheets on the collating board.

Variations may be resorted to within the scope of the invention, and portions of the improvements may be used without others.
